You can look at this extension: *Bookmarks Deiconizer: https://addons.mozilla.org/firefox/addon/bookmarks-deiconizer/

Thanks. But that removes them from the bookmarks toolbar. I want to remove them from the tabs.

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

/* Tabs: no icons */
.tabbrowser-tabs .tab-icon-image { display: none !important; }

/* Bookmarks Toolbar: no icons */
#personal-bookmarks .toolbarbutton-icon { display: none !important; }

I use code in userChrome.css to achieve that. What the Bookmarks Deiconizer extension does can also be done with code in userChrome.css by the way. Add code to userChrome.css below the @namespace line. * http://kb.mozillazine.org/userChrome.css * http://kb.mozillazine.org/Editing_configuration * ChromEdit Plus: http://webdesigns.ms11.net/chromeditp.html ---- <pre><nowiki>@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */ /* Tabs: no icons */ .tabbrowser-tabs .tab-icon-image { display: none !important; } /* Bookmarks Toolbar: no icons */ #personal-bookmarks .toolbarbutton-icon { display: none !important; } </nowiki></pre>

Perfect! Thank you.

You're welcome
